Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

The Nieuwe Maas is a major river in the Netherlands, flowing through the city of Rotterdam and acting as one of the key branches of the River Rhine. It connects the Rotterdam harbor area to the North Sea, making it one of the busiest shipping routes in Europe. The water temperature in the Nieuwe Maas varies seasonally. During the summer months, the temperature typically ranges from 15°C to 20°C (59°F to 68°F), with the warmest conditions usually found in July and August. In the winter, temperatures can drop to between 4°C and 8°C (39°F to 46°F), with the coldest months being December through February.
Swimming in the Nieuwe Maas is not recommended due to its heavy use for industrial and commercial shipping. The river is characterized by strong currents, and the water quality can be affected by pollution from ships, urban runoff, and industrial waste. Additionally, the Nieuwe Maas is a highly trafficked waterway, with large vessels constantly moving, making it dangerous for recreational swimming. For safe swimming, individuals usually opt for designated beaches or lakes away from busy shipping channels.
